This invention relates to flyers for silk spinning machines, and has forone of its objects to provide a device of this character which willembody comparatively few parts of simple construction and capable ofbeing manufactured and assembled in a comparatively short time and atlittle expense.

The invention has for a further object to provide a flyer which willembody an anchoring sleeve provided with an outer annular shoulder, anda spring secured within the sleeve and adapted to retain it upon aspindle against accidental displacement. 7

The invention has for a further object to provide a flyer which willembody a journal sleeve adapted to be supported upon the anchoringsleeve by said shoulder and retained upon the, anchoring sleeve by saidspring.

The invention has for a further object to provide a fiyer which willembody a base plate adapted to be rotatably supported upon the journalsleeve by outer shoulders formed upon said sleeve and contacting withthe upper and lower sides of said base plate.

The invention'has for a still further object to provide a fiyer whereinthe base plate shall be provided with means adapted to permit the flyerwires to be secured thereto easily and quickly and in a firm manner.

With the foregoing and other objects in View, the nature of which willappear as the description proceeds, the invention con- 3 sists in theconstruction, combination and arrangement of parts hereinafter fullydescribed and claimed, and illustrated in the accompanying drawing,wherein:

Referring in detail to the drawing, 1 designates one of the uprightspindles of a spinning machine, 2 a bobbin mounted upon the spindle, and3 the fiyer.

The fiyer 3 comprises an anchoring sleeve 4 which is mounted upon thespindle above the bobbin 2. A vertical slot 5 is formed in the lower endportion of the anchoring sleeve 1, and circumferentially spaced verticalslots 6 and 7 are formed in the upper end portion of the sleeve. Theslots 5, 6 and 7 are closed at their ends, and the lower slot 5 isarranged in a vertical plan passing centrally between the upper slots 6and 7. An outwardly extending shoulder 8 of annular formation, is formedupon the anchoringsleeve 4 between thehorizontal center of the sleeveand the slot 5; V

A journal sleeve 9 which is split longitudinally, is supported upon theanchoring sleeve 4 by the shoulder 8. The journal sleeve 9 is providedat opposite sides of its horizontal center with outwardlyextendingshoulders 10 and 11 of annular formation. A baseplate 12 having asubstantially circular central portion or hub 13, and arms 14 extendingin opposite directions from the hub and increasing in width in thedirection of their outer ends, is provided in its hub with an opening 15for the recept-ion of the journal sleeve 9. The base plate 12 isrotatably supported on the journal sleeve 9 by the shoulders 10 and 11which contact with the upper and lower sides of the hub 13. The arms 14are provided at their inner ends with openings 16, and are provided attheir outer ends with longitudinally spaced pairs of retaining elementsor clips 17. The right twist fiyer wire 18 and the left twist flyer wire18 are of V-form, and are arranged upon the arms 1d. With their apexesinnermost. The apex j the openings 16.

The sides of the flyer wires 18 and 18 are arranged beneath the clips 17which are formed integrally with the arms 14. One side of each flyerwire terminates in a thread engaging eye 20, and the other sides thereofare provided with downwardly extending arms 21 terminally provided withthread engaging eyes 22. The eyes 20 and 22 of each flyer wire arearranged in parallel vertical planes.

A spiraled spring 28 tapering in the direction of its upperend and madefrom flat stock, is arranged within the anchoring sleeve 4. The spring23 receives the spindle 1, and during the application of the flyer tothe spindle the spring is tensioned so as to establish sufficientfriction between it and the spindle to hold the flyer against accidentaldisplacement. The spring 23 is connected to the anchoring sleeve 4 in amanner to prevent the anchoring sleeve from having any rotary movementwith respect thereto. This connection is established by passing thelower'end of the spring through the slot 5 and bending it into contactwith the outer side of the anchoring sleeve, as shown at 24, and bypassing the upper end portion of a spring through the slot 6, bendingsaid end portion about the outer side of the anchoring sleeve, as shownat 25, and by then carrying the free end of the spring .nected therewithin the manner stated.

back into the anchoring sleeve through the slot 7, as shown at 26. Thespring portion,

25 lies against the outer side of the anchoring sleeve 4 above thejournal sleeve 9, and serves to maintain the journal sleeve on theanchoring sleeve. V

In practice, the=journal sleeve 9 and base plate 12 are first assembled,and this may be readily done since the journal sleeve is splitlongitudinally. These assembled parts are then applied to the anchoringsleeve 4, and this is done by sliding the journal sleeve 9 upon theanchoring sleeve until it contacts with the shoulder 8. The spring 23 isthen inserted in the anchoring sleeve 4 and con- If desired, the flyerwires 18 and 18 may be applied to the base plate 12 before or after theapplication of the base plate to the journal sleeve 9. To connect theflyer wires 18 and 18 to the base plate 12, it is only necessary toengage the angular ends 19 of the flyer wires with the projections 16 ofthe base plate, swing the flyer wires into contact with the upper sidesof the arms 14, and then bend the clips 17 into contact with the sidesof the fiyer wires. It will be understood that the parts of the devicesare connected together in. a very simple manner While I have describedthe principle of operation of the invention, together with the devicewhich I now consider to be the best embodiment thereof, I desire to haveit understood that the device shown is merely illustrative, and thatsuch changes may be made when desired as are within the scope of theinvention as claimed.

What I claim is:

base plate connected to the journal sleeve,

and flyer wires connected to the base plate.

8.

. 4. A flyer comprising a journal sleeve provided with vertically spacedand outwardly extending shoulders, a base plate having a hub arrangedbetween said shoulders and provided with arms having openings and clips,and flyer wires engaged by said clips and having angular portionsextending through the said openings.

7. A flyer comprising right and left flyer wires, each wire embodyingtwo sides, one side terminating in a thread engaging eye,

the other side terminating in a downwardly extending arm which in turnterminates in a thread engaging eye, a base plate provided withopenings, said fiyer wires connected to said base plate and havingangular ends passing through said openings, as and for the purposes setforth.

8. A flyer comprising right and left flyer wires, each wire embodyingtwo sides, one side terminating in a thread engaging eye, the other sideterminating in a downwardly extending arm which in turn terminates in athread engaging eye, a base plate provided with openings, said flyerwires connected to said base plate and having angular ends passingthrough said openings, and projections carried by said base plate andengaging the angular ends of the fiyer wires, as and for the purposesset forth.

9. A fiyer comprising an anchoring sleeve, flyer wires, means adapted torotatably connect the flyer Wires to the sleeve, and a spiral springarranged within the sleeve and having its ends secured thereto, saidspring tapering in the direction of its upper end and adapted tofrictionally engage a spindle, as and for the purposes set forth.

10. A flyer comprising a base plate provided with pairs of oppositelyextending projections, and a fiyer wire resting upon the base plate andsaid oppositely extending projections engaging said wire for retainingthe wire in engagement with said base plate.
